Hi my name is ashley, i weigh 145 and i m 18. I was diagnosed with strep throat about 4 weeks ago and was put on amoxicillin for 10 days, skipped two days but finished the antibiotic. It came back the week after I finished but didn t test positive for it, so I was put on Augmentin for 10 days and nasonex for a month. I just finished the augmentin two days ago and my throat is getting sore again, I don t know what this is?
